Description

Technical Field

[0001] This utility model relates to the technical field of aluminum rod manufacturing equipment, and in particular to a cover plate opening and closing structure for an aluminum rod casting machine. Background Technology

[0002] When using an aluminum rod casting machine, hydraulic cylinders are typically used to open and close the cover plate. However, the high temperatures during aluminum rod casting can damage the hydraulic cylinders, leading to frequent leaks due to poor sealing. This not only requires frequent hydraulic cylinder repairs but also disrupts production schedules.

[0003] Currently, a wire rope pulling device has been developed to open and close the cover plate. This device includes a drum with a wound wire rope and a motor that drives the drum via a reducer. However, this device still has the following drawbacks: 1. The angle between the wire rope and the cover plate in the closed state is small, resulting in significant stress on the wire rope when opening the cover plate, often leading to breakage; 2. Even when the motor is off, its output shaft continues to rotate due to inertia, making it difficult to effectively control the degree of cover plate opening.

[0004] To address this, we designed a cover plate opening and closing structure for an aluminum rod casting machine. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a cover plate opening and closing structure for an aluminum rod casting machine.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A cover plate opening and closing structure for an aluminum rod casting machine includes a base. The top of the base is equipped with a drum wound with a steel wire rope, a motor, and a speed reducer. The outer end of the steel wire rope is connected to the end face of the cover plate's opening and closing end. The motor's output shaft and the speed reducer's input shaft are driven by a belt drive. A brake is provided on the base corresponding to the speed reducer's input shaft to brake the input shaft and fix the cover plate's position. A crank handle is provided on the outer end of the speed reducer's input shaft to manually rotate the shaft and adjust the cover plate's opening and closing degree.

[0008] Preferably, the speed reduction device includes a worm gear reducer whose input shaft is driven to the output shaft of a motor via a belt assembly, and a gear reducer whose input shaft is driven to the output shaft of the worm gear reducer, wherein the output shaft of the gear reducer is driven to a drum.

[0009] Preferably, both the brake and the crank handle are connected to the input shaft of the worm gear reducer.

[0010] Preferably, it also includes an adjustment device for adjusting the angle between the wire rope and the cover plate.

[0011] Preferably, the adjustment device includes a slide rail pair disposed above the cover plate and perpendicular to the rotation center axis of the cover plate. A movable pulley is provided below the sliding part of the slide rail pair for the wire rope to pass over, so as to adjust the angle between the wire rope and the cover plate by changing the position of the movable pulley.

[0012] Preferably, the sliding part of the slide rail pair is provided with rollers that roll in cooperation with the slide rail part.

[0013] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0014] 1. The cover plate opening degree can be adjusted by manually rotating the input shaft of the speed reduction device through the crank structure after the motor is turned off, using the brake and crank structure in conjunction. Then, the input shaft of the speed reduction device can be braked by the brake to achieve the function of controlling the opening and closing of the cover plate to any desired degree.

[0015] 2. The adjustment device can change the position of the sliding part of the slide rail pair to adjust the angle between the wire rope and the cover plate, so that the angle between the wire rope and the cover plate is as close as possible or as right angle, thereby reducing the tensile force on the wire rope when pulling the cover plate, thus effectively preventing the wire rope from breaking.

[0021] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if terms such as "upper", "lower", "front", "rear", "left", "right" indicate orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention. It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component. That is, "end" indicates the head and tail area in the length direction of the corresponding component, and "side part" indicates the head and tail area in the width direction of the corresponding component. They are used for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation.

[0022] Example 1, in conjunction with Appendix Figure 1-3 A cover plate opening and closing structure for an aluminum rod casting machine includes a base 1. The top of the base 1 is provided with a drum 3 on which a steel wire rope 2 is wound, a motor 4 and a speed reduction device 5. The outer end of the steel wire rope 2 is connected to the end face of the opening and closing end of the cover plate. Specifically, the base 1 is located outside the hinge end of the cover plate. The top surface of the base 1 is provided with a drum 3 on one side of the cover plate and the other side of the top surface of the base 1 is provided with a motor 4.

[0023] The output shaft of motor 4 is connected to the input shaft of reduction gear 5 via a belt assembly 6. A brake 7 is provided on the base 1 corresponding to the input shaft of reduction gear 5, which can brake the input shaft of reduction gear 5 to fix the position of the cover plate. A crank handle 8 is provided at the outer end of the input shaft of reduction gear 5, allowing manual rotation of the input shaft to adjust the opening and closing degree of the cover plate. In other words, motor 4 drives the input shaft of reduction gear 5 to rotate via belt assembly 6, thereby reducing the speed of reduction gear 5. The output shaft of reduction gear 5 slowly drives the drum 3 to rotate, thus slowly winding and unwinding the wire rope 2, achieving the function of slowly opening and closing the cover plate.

[0024] As needed, the belt assembly 6 includes a pulley fixedly mounted on the output shaft of the motor 4 and a pulley fixedly mounted on the input shaft of the reduction gear 5, with the two pulleys connected by a belt; as needed, the belt assembly 6 also has a protective housing.

[0025] Preferably, brake 7 is a crane brake.

[0026] As needed, to increase the reduction ratio, the reduction device 5 includes a worm gear reducer 51 whose input shaft is driven and connected to the output shaft of the motor 4 via a belt assembly 6, and a gear reducer 52 whose input shaft is driven and connected to the output shaft of the worm gear reducer 51. The output shaft of the gear reducer 52 is driven and connected to the drum 3. Preferably, to reduce the difficulty of manually rotating the drum 3, both the brake 7 and the crank handle structure 8 are connected to the input shaft of the worm gear reducer 51.

[0027] Example 2, in conjunction with Appendix Figure 1-2 4. A cover plate opening and closing structure for an aluminum rod casting machine, based on embodiment 1, further includes an adjusting device 9 for adjusting the angle between the wire rope 2 and the cover plate.

[0028] The adjusting device 9 includes a slide rail pair 91 located above the cover plate and perpendicular to the rotation center axis of the cover plate; a movable pulley 92 is provided below the sliding part of the slide rail pair 91 for the wire rope 2 to pass over, so as to adjust the angle between the wire rope 2 and the cover plate by changing the position of the movable pulley 92.

[0029] As required, the slide rail part of slide rail pair 91 is a linear slide rail; preferably, one end of the slide rail part of slide rail pair 91 is located directly above the connection between the cover plate and the wire rope 2, and the other end of the slide rail part of slide rail pair 91 is located outside the hinge end of the cover plate.

[0030] It should be noted that the slide rail pair 91 also has a drive device for moving the sliding part of the slide rail pair 91, which can be a lead screw motor, hydraulic cylinder, etc.

[0031] This configuration allows the wire rope 2 to move directly above the connection point between the cover plate and the steel wire rope 2 via the sliding part of the slide rail pair 91 before the cover plate is opened. At this time, the steel wire rope 2 and the cover plate form a 90-degree angle. Compared with the steel wire rope 2 and the cover plate forming an acute angle, this reduces the force exerted by the steel wire rope 2 to open the cover plate, effectively solving the technical problem of the steel wire rope 2 breaking due to excessive tension.

[0032] As needed, the sliding part of the slide rail pair 91 is provided with a roller 93 that rolls with the slide rail part.

[0033] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
